Earlier last night, cryptocurrency exchange Binance announced that its BNB Chain (BSC) network has been halted.
Binance stated that after the attack on the network’s official cross-chain bridge, it will stop deposits and withdrawals made through BNB Chain. After the attack, work started to open the network.
BNB Chain Suffered from Cross-Chain Attack
As Binance founder and CEO Changpeng Zhao (CZ) reported, a vulnerability in BSC Token Hub, a cross-chain bridge, affected BNB.
In the statements made by BNB Chain, immediately after the attack by exploiting the vulnerability, it was stated that BSC was temporarily paused due to uncontrolled activity and an update would be made.

Activation efforts were first initiated by asking all validators to temporarily suspend the BSC. At the same time, it was announced that the attack was under control and the funds were safe.
Urgent Update Call from Binance to Nodes
BNB Chain has requested that BSC validators contact them so that a Node upgrade can be scheduled.
The Binance team, which has been working to activate the network since night hours, shared the latest version for BSC Nodes this morning. It also announced that they are working in coordination to activate BNB Chain within 1 hour.
